Daily nesting
One steel plate and a set of parts every day: drag them onto the plate, rotate, and fill it as full as you can. Everyone gets the same puzzle, and submitting earns fragments once a day.
Nesting Pro
Parts arrive one at a time and you only see the next three: place one, get the next, no undo. The sheet also has a few defect cells you can't cut. 3 runs a day, your best run is ranked.
Torch path
A steel plate with the parts already nested: pick the cutting order and start corners to keep the torch's dead travel as short as possible. Everyone gets the same puzzle, and submitting earns fragments once a day.
Torch path Pro
A whole sheet packed with parts, timed with fiber laser machine figures: shared edges are settled by the nesting, and you choose how each cut starts, with a pierce, a bridge cut or a plate-edge start. Two boards, total distance and total time, plus a daily fragment reward.
Bar cutting
A daily cutting list: the yard holds stock bars and offcuts, and you assign every part to a bar. The less stock you use, the higher you rank. Everyone gets the same puzzle, and submitting earns fragments once a day.
Weld race
One portal-frame column or rafter a day: click the seams in 3D to set the welding order and race the pre-planned robot on total time. Same puzzle for everyone; playing earns mechanical fragments.
